DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
This invention relates generally to eyeglasses and more particularly to an eyeglass frame which presents a striking ornamental appearance.
Eyeglasses are a necessary accessory to the many people who suffer from various forms of vision impairment. While eyeglass frames are available in a wide variety of styles and colors, eyeglass frames in general continue to have a form that closely follows function and continue to present a largely pragmatic appearance.
SUMMARY OF THE INVENTION
The present invention is directed to the provision of an eyeglass frame which is structured to provide a unique and striking ornamental effect.
The eyeglass frame of the invention is of the type including lens frame portions and temple portions. According to the invention, at least one of these portions is hollow and formed of a non-opaque material and a colored material is positioned within the hollow portion to impart the color of the material to the hollow portion.
According to a further feature of the invention, the eyeglass frame is made from a single, continuous piece of tubular plastic selectively configured to successively define the first temple portion, the first lens portion, the second lens portion, and the second temple portion so as to thereby define a single passage extending continuously through the frame portions.
According to a further feature of the invention, the colored material is a colored liquid and the respective free ends of the temple portions are sealed to trap the colored liquid within the continuous passage.
In one embodiment of the invention, the piece of tubular plastic is formed of a thermoplastic material and the ends of the temple portions are permanently sealed in a heat sealing operation.
In another embodiment of the invention, the free ends of the temple portions are temporarily sealed by plugs received in the free ends so that various colored liquids may be selectively injected into and removed from the continuous passage to provide a variety of appearances to the frame.
In another embodiment of the invention, the eyeglass frame further includes a tubular back portion interconnecting the free ends of the temple portions and coacting with the lens frame portions and the temple portions to define a continuous closed loop tubular passage. The colored liquid trapped in the passage is thus free to flow freely and totally around the eyeglass frame in response to movement of the frame on the head of the user.
According to a further aspect of the invention, glitter particles are dispersed in the colored liquid to heighten the ornamental effect provided by the eyeglass frame.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to FIG. 1, the eyeglass frame 10 of the present invention preferably employs a continuous, hollow transparent tube formed into a first temple piece 12, a first lens frame 14, a nose bridge portion 16, a second lens frame 18, and a second temple piece 20. The frame is preferable made of a thermoplastic tubing which may be shaped or formed with the application of heat, but which ultimately sets into a relatively rigid form.
The tube forms a hollow passage 22 which runs through the entire length of
